Abstract

Although no widely accepted definition of the term “quality of life” exists, the close relationship between quality of life and health is accepted. In recent years, there has been a growing interest in the assessment of quality of life in both medical care and clinical trials. Measures which have often been used in evaluating quality of life are for example the two self-rating questionnaires the Nottingham Health Profile (NHP) and the Psychological General Well-Being Index (PGWB).
